a. The standard measure used to approximate the number of fibres of a whole muscle is called Physiological Cross-Sectional Area (PCSA). The PCSA is the area of a slice that passes through all the fibres of a muscle.
b. The PCSA is calculated using the following formula :
PCSA (cm2) = muscle mass (g). cosine θ / ρ (gcm-3) x fibre length ( in cm)
Here, ρ represents muscle density and θ represents surface pennation angle.
c. With small and large values of PCSA, the maximum tetanic tension lowers and increases respectively. The force length curve has the same shape in both cases where the curve is shifted upward in case of a muscle with higher PCSA.

The length of time Y necessary to complete a key operation in the construction of houses has an exponential distribution with mean 17 hours. The formula C = 100 + 80Y + 3Y2 relates the cost C of completing this operation to the square of the time to completion. The mean of C was found to be found to be 3,194 hours and the variance of C was found to be 26,316,340. How many standard deviations above the mean is...
